✦ Synopsis

In our previous studiesL on the preparation and reactions of dianions (Equation l), we reported the quantitative conversion of cr, B-unsaturated carboxylic acids (I) to their S, Y-isomers (III) through formation of the stable intermediate dianion (II). The dianions were prepared by reaction of the appropriate carboxylic acid with lithium diisopropylamide (butyl lithium-diisopropylamine) in
